Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Poly[oxy(methyl-1,2-ethanediyl)], .alpha.,.alpha.'-1,2-ethanediylbis[.omega.-hydroxy-, polymer with .alpha.-hydro-.omega.-hydroxypoly[oxy(methyl-1,2-ethanediyl)] and 1,1'-methylenebis[isocyanatobenzene].
Poly[oxy(methyl-1,2-ethanediyl)], .alpha.,.alpha.'-1,2-ethanediylbis[.omega.-hydroxy-, polymer with .alpha.-hydro-.omega.-hydroxypoly[oxy(methyl-1,2-ethanediyl)] and 1,1'-methylenebis[isocyanatobenzene] (CAS 68092-68-2), molecular formula C15H10N2O2C8H18O4C3H8O2 and molecular weight 504.58 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Poly[oxy(methyl-1,2-ethanediyl)], .alpha.,.alpha.'-1,2-ethanediylbis[.omega.-hydroxy-, polymer with .alpha.-hydro-.omega.-hydroxypoly[oxy(methyl-1,2-ethanediyl)] and 1,1'-methylenebis[isocyanatobenzene] is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 504.58 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.
As a certified reference material (CRM), Poly[oxy(methyl-1,2-ethanediyl)], .alpha.,.alpha.'-1,2-ethanediylbis[.omega.-hydroxy-, polymer with .alpha.-hydro-.omega.-hydroxypoly[oxy(methyl-1,2-ethanediyl)] and 1,1'-methylenebis[isocyanatobenzene] 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.
