Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Amino-2-chlorobenzenethiol hydrochloride.
CATO supplies 3-Amino-2-chlorobenzenethiol hydrochloride (CAS 2055759-81-2), a certified reference material (molecular formula C6H6ClNSHCl, MW 196.09 g/mol) for analytical method development and quality control.
Structurally, 3-Amino-2-chlorobenzenethiol hydrochloride (C6H6ClNSHCl) contains a nitrile group, sulfur-containing functionality, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 196.09 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
