Chemical Structure
Description
The occurrence of L-Arginine-2，3，3，4，4，5，5-d7 HCl is closely related to deuterium isotope labeling, an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies L-Arginine-2，3，3，4，4，5，5-d7 HCl (CAS 204244-77-9), a certified reference material (molecular formula C6H7D7N4O2HCl, MW 217.70 g/mol) for analytical method development and quality control.
Owing to deuterium isotope labeling, an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, L-Arginine-2，3，3，4，4，5，5-d7 HCl is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 217.70 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures L-Arginine-2，3，3，4，4，5，5-d7 HCl 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.
