- Scale-up screening, where the same chemistry is later transferred to a larger batch
Reading the specification
This is a research-scale speciality product, and the specification reflects that: assay by HPLC or GC is the primary line, with appearance used as the practical ageing indicator. For air- or moisture-sensitive items in this group the packaging and the headspace matter as much as the assay, and for the strongly alkylating or pyrophoric items the handling section below is part of the product, not an accessory to it.
Packaging and supply
Supplied in research quantities from 1 g and 5 g through 25 g and 100 g, with scale-up to bulk packed under nitrogen or argon where the product allows it. Every lot ships with a batch COA and the current SDS, FOB or CIF against destination. If you need a specific assay method, a water limit, an enantiomeric purity figure or a metal-residue limit, state it at enquiry stage – the batch documentation is issued against the specification you agree.
Handling: This product is sensitive to air and moisture. Phosphines oxidise to the corresponding phosphine oxide on exposure to air, and the oxide is a different – usually inactive – ligand, so keep containers sealed under nitrogen or argon, handle with Schlenk or glovebox technique, and check the 31P NMR of a stored sample if a container has been open for some time. Refer to the SDS for the full hazard profile.
