Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (5-bromo-1-methyl-pyrazol-3-yl)methyl methanesulfonate.
(5-bromo-1-methyl-pyrazol-3-yl)methyl methanesulfonate (CAS 2303766-93-8) is a high-purity analytical reference standard with the molecular formula C6H13BrN2O3S and a molecular weight of 273.15 g/mol.
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, (5-bromo-1-methyl-pyrazol-3-yl)methyl methanesulfonate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 273.15 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.
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), (5-bromo-1-methyl-pyrazol-3-yl)methyl methanesulfonate 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.
