For procurement managers and R&D scientists in the pharmaceutical and fine chemical industries, understanding detailed chemical specifications is paramount. It ensures that the materials purchased will perform as expected in complex synthesis processes. This guide will help demystify the key specifications for 2',2'-Difluoro-2'-deoxycytidine-3',5'-dibenzoate (CAS 134790-39-9), a crucial intermediate, from the perspective of a leading manufacturer and supplier.

1. Chemical Name and Synonyms: Clarity in Identification

The primary identifier is its IUPAC name: 2',2'-Difluoro-2'-deoxycytidine-3',5'-dibenzoate. However, you'll often encounter numerous synonyms, such as Gemcitabine T9 Intermediate, Chloropurine riboside, or GeMcitabine Intermediate 9. These arise from different naming conventions or proprietary designations. As a manufacturer, we ensure our documentation clearly states the primary name and common synonyms to avoid confusion and facilitate precise sourcing.

2. CAS Number: The Unique Fingerprint

The Chemical Abstracts Service (CAS) registry number, 134790-39-9, is a unique numerical identifier. This is the most critical piece of information for precisely identifying the chemical, independent of its name or synonyms. When you 'buy 2',2'-Difluoro-2'-deoxycytidine-3',5'-dibenzoate,' always confirm the CAS number to ensure you are procuring the exact compound required.

3. Molecular Formula and Weight: The Building Blocks

The molecular formula, C23H19F2N3O6, and molecular weight, 471.41 g/mol, describe the atomic composition and mass of the compound. These are fundamental properties used in stoichiometric calculations for synthesis. Manufacturers use these to verify the compound's identity and purity through analytical methods.

4. Purity: The Crucial Metric

Purity is arguably the most important specification for pharmaceutical intermediates. It is typically expressed as a percentage (e.g., >=98.5% or >=99%). Higher purity means fewer unwanted by-products, leading to more efficient downstream reactions and a cleaner final API. As a 'high purity difluorocytidine dibenzoate supplier,' we provide detailed purity analysis, often using High-Performance Liquid Chromatography (HPLC). Our commitment is to deliver material that meets or exceeds your specified purity requirements.

5. Appearance: Visual Confirmation

The appearance, often described as a 'Tan solid' or 'Off-white solid,' provides a basic visual confirmation of the product's physical state. While subjective, significant deviations from the expected appearance can indicate storage issues or contamination.

6. Melting Point: A Signature Property

The melting point range (e.g., 229-232°C) is a characteristic property of a pure crystalline solid. A sharp melting point range typically indicates high purity. Manufacturers use this as a quality control check. When seeking a reliable 'pharmaceutical intermediate manufacturer,' inquiring about the typical melting point range is a good practice.

7. Solubility: Practical Application Data

Information on solubility (e.g., in DMSO) is crucial for understanding how the compound will behave in reaction solvents. This practical data helps formulators and chemists plan their processes effectively. We provide this information to aid in your application development.

Understanding these specifications empowers you to make informed purchasing decisions. When you source 2',2'-Difluoro-2'-deoxycytidine-3',5'-dibenzoate from a trusted manufacturer in China, like us, you receive comprehensive documentation that clarifies these critical parameters, ensuring your research and production initiatives proceed smoothly.
