For professionals in the chemical and pharmaceutical industries, understanding detailed product specifications is non-negotiable. 6-Chloro-L-Tryptophan, identified by CAS 33468-35-8, is a compound that requires precise attention to its chemical characteristics to ensure its effective use. This article delves into the key specifications of this important intermediate, highlighting why sourcing from a quality-conscious manufacturer is essential when you plan to buy.

The Molecular Foundation: Formula and Weight

6-Chloro-L-Tryptophan has the molecular formula C11H11ClN2O2. This formula provides a blueprint of the atoms that constitute the molecule, including carbon, hydrogen, chlorine, nitrogen, and oxygen. Its molecular weight is approximately 238.67 g/mol. This precise molecular weight is critical for stoichiometric calculations in synthesis and for analytical identification purposes. When procuring this compound, you can expect these fundamental specifications to be clearly listed by any reputable supplier.

Purity: The Cornerstone of Quality

Beyond its basic composition, the purity of 6-Chloro-L-Tryptophan is arguably its most significant specification for its intended applications, particularly in pharmaceutical research and synthesis. Many sources indicate a purity level exceeding 95% (often determined by HPLC). This high level of purity ensures that the compound will perform reliably in complex reactions and that unwanted side products are minimized. For any researcher or formulator looking to purchase this material, verifying the purity percentage is a primary step in evaluating a manufacturer's capability and product quality.

Key Physical and Chemical Properties

In addition to molecular composition and purity, other properties are important for handling and application:

  • Appearance: Typically described as an off-white to pale beige solid. This visual cue can be an initial indicator of quality, though analytical testing is definitive.
  • CAS Number: 33468-35-8, a unique identifier ensuring you are referencing the correct chemical substance.
  • Molecular Structure: Understanding its indole ring structure with a chlorine substituent and an amino acid side chain provides insight into its reactivity and potential applications.

When you are ready to buy 6-Chloro-L-Tryptophan, obtaining a detailed Certificate of Analysis (CoA) from your chosen supplier is essential. This document will confirm all critical specifications, including purity, CAS number, molecular formula, and any specific analytical data obtained during quality control. Partnering with a dedicated manufacturer who prioritizes transparency in their product specifications ensures that your procurement process is informed and your research or production goals can be met with confidence.
