Chemical Structure
Description
The occurrence of 4-Amino-3,3-difluoro-2-methylbutan-2-ol hydrochloride is closely related to an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4-Amino-3,3-difluoro-2-methylbutan-2-ol hydrochloride (CAS 2089649-04-5), a certified reference material (molecular formula C5H11F2NOHCl, MW 175.60 g/mol) for analytical method development and quality control.
Owing to an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 4-Amino-3,3-difluoro-2-methylbutan-2-ol hydrochloride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 175.60 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.
As a certified reference material (CRM), 4-Amino-3,3-difluoro-2-methylbutan-2-ol hydrochloride 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.
