Chemical Structure

(3-amino-4-chloro-1H-pyrazol-1-yl)acetic acid,2HCl CAS 1431968-09-0 chemical structure

Description

The occurrence of (3-amino-4-chloro-1H-pyrazol-1-yl)acetic acid,2HCl is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(3-amino-4-chloro-1H-pyrazol-1-yl)acetic acid,2HCl (CAS 1431968-09-0), molecular formula C5H6ClN3O2HCl and molecular weight 212.03 g/mol, is a CATO reference standard with documented purity and traceability.

(3-amino-4-chloro-1H-pyrazol-1-yl)acetic acid,2HCl (C5H6ClN3O2HCl) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), (3-amino-4-chloro-1H-pyrazol-1-yl)acetic acid,2HCl meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
