6-Chloro-2-Picoline Thermo Scientific Alternative Supplier
Verifying CAS 18368-63-3 Purity Versus Fisher Scientific AC152230010 Lots
When procuring 6-Chloro-2-picoline for industrial synthesis or R&D applications, verifying the Chemical Abstracts Service (CAS) registry number is the primary step in quality assurance. The identifier CAS 18368-63-3 corresponds strictly to 2-chloro-6-methylpyridine. In the context of sourcing alternatives to legacy catalog items such as Fisher Scientific AC152230010, procurement managers must ensure that the molecular identity remains consistent regardless of the supplier branding. Variations in synthesis routes can introduce different trace impurity profiles, even if the primary assay percentage appears identical on a certificate of analysis.
At NINGBO INNO PHARMCHEM CO.,LTD., we prioritize batch-to-batch consistency for this pyridine derivative. While legacy catalog lots may have served as historical benchmarks, reliance on single-source catalog items often introduces supply chain fragility. Verifying purity involves more than a simple GC area percentage; it requires confirming the absence of isomeric contaminants that could interfere with downstream coupling reactions. Our quality control protocols focus on maintaining the structural integrity of the chlorinated picoline molecule throughout the manufacturing and storage process.
Physical and Chemical Technical Specifications for 6-Chloro-2-picoline Thermo Scientific Alternatives
Understanding the physical properties of 6-methyl-2-chloropyridine is critical for process engineering and reactor design. Based on standard chemical data, the molecular formula is C6H6ClN with a molecular weight of 127.57 g/mol. The substance typically presents as a colorless to yellow liquid. Standard reference data indicates a density of approximately 1.1600 g/mL and a refractive index ranging between 1.5260 and 1.528. The boiling point is generally observed between 64°C and 68°C at a reduced pressure of 10.0 mmHg.
From a field engineering perspective, there is a non-standard parameter that often goes unreported on basic COAs but significantly impacts handling: thermal-induced color stability during transit. Chlorinated pyridines can exhibit sensitivity to prolonged exposure to ambient light and elevated temperatures during summer shipping. We have observed that without proper UV-stabilized packaging or temperature-controlled logistics, the APHA color value can shift from colorless to a deeper yellow over time, even if the chemical purity remains unaffected. This visual change does not necessarily indicate degradation of the active molecule, but it can trigger unnecessary quality rejects at the receiving end if not documented. Our team monitors this parameter closely to ensure the organic intermediate arrives within acceptable visual specifications.
Critical COA Parameters for 98% Purity Grades Versus Fisher Scientific Lots
For R&D managers comparing potential sources, the Certificate of Analysis (COA) is the definitive document for validation. While historical lots from major catalog suppliers set a baseline, industrial-scale procurement requires rigorous verification of key technical parameters. It is essential to note that specific numerical values can vary slightly by batch. Please refer to the batch-specific COA for exact figures regarding your shipment.
The following table outlines the critical technical parameters typically evaluated for 98% purity grades of this chemical intermediate:
| Parameter | Typical Specification Range | Testing Method |
|---|---|---|
| Assay (GC) | 97.5% - 99.0% | Gas Chromatography |
| Water Content | < 0.5% | Karl Fischer Titration |
| Density (20°C) | 1.15 - 1.17 g/mL | ASTM D4052 |
| Refractive Index (20°C) | 1.526 - 1.528 | ASTM D1218 |
| Appearance | Colorless to Light Yellow Liquid | Visual / APHA |
When evaluating alternatives, ensure that the testing methods align with your internal quality standards. Discrepancies in GC column type or temperature programming can yield different area percentages for the main peak versus impurities.
Bulk Packaging Configurations for 6-Chloro-2-picoline Beyond AC152230010 Units
Legacy catalog items are often restricted to small-scale laboratory packaging, such as glass bottles, which are inefficient for pilot plant or commercial production. Scaling up requires robust physical packaging solutions that ensure safety and minimize waste. We supply 6-Chloro-2-picoline in configurations designed for industrial logistics, moving beyond single-unit glass containers.
Standard bulk options include 200L steel drums lined with appropriate resistant materials to prevent corrosion or contamination. For larger volume requirements, IBC (Intermediate Bulk Container) totes are available. These configurations are selected based on the physical shipping method and the destination port's handling capabilities. Proper sealing is critical to prevent moisture ingress, which can affect the water content specification upon arrival. All packaging is labeled with clear hazard communication consistent with global transport regulations, focusing strictly on physical safety and handling instructions.
Impurity Profile Limits for 6-Chloro-2-picoline in Thermo Scientific Alternatives
The impurity profile is perhaps the most critical differentiator between generic chemical suppliers and specialized manufacturers. In the synthesis of 2-chloro-6-methylpyridine, potential impurities include unreacted starting materials, over-chlorinated byproducts, or isomeric picolines. These trace components can act as catalyst poisons or interfere with subsequent substitution reactions in pharmaceutical or agrochemical synthesis.
Our manufacturing process controls focus on minimizing these specific organic impurities. While a standard COA may only list the main assay percentage, advanced quality control involves tracking specific known byproducts. For critical applications, we recommend requesting a comprehensive impurity breakdown. This level of transparency ensures that the chemical supplier provides material suitable for sensitive organic synthesis routes without requiring additional purification steps that increase cost and lead time.
Frequently Asked Questions
What is the minimum order quantity for bulk 6-Chloro-2-picoline?
Our minimum order quantity depends on the packaging configuration selected. For drum shipments, typical MOQs start at one full drum. Please contact our sales team for specific volume requirements related to IBC or isotank shipments.
Can you provide a COA before shipment?
Yes, a batch-specific Certificate of Analysis is available upon request prior to shipment. This document will detail the exact assay, water content, and physical parameters for the lot reserved for your order.
What is the typical lead time for production and shipping?
Lead times vary based on current inventory levels and production scheduling. Standard ex-stock items can ship within days, while made-to-order batches may require additional production time. Our procurement specialists will provide a confirmed timeline upon inquiry.
How should this chemical be stored upon arrival?
6-Chloro-2-picoline should be stored in a cool, dry, and well-ventilated area away from direct sunlight. Containers must be kept tightly closed to prevent moisture absorption and maintain quality standards.
