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 Ethyl 2,2-difluoro-3-aminopropanoate hydrochloride.
Ethyl 2,2-difluoro-3-aminopropanoate hydrochloride (CAS 541547-37-9), molecular formula C5H9F2NO2HCl and molecular weight 189.59 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, Ethyl 2,2-difluoro-3-aminopropanoate hydrochloride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 189.59 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures Ethyl 2,2-difluoro-3-aminopropanoate hydrochloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
