Building blocks index
The whole catalogue in one list: 283 entries with CAS number, molecular formula, molecular weight and standard packing. Sorted alphabetically so an entry can be found from a route step without knowing its group.
Reading an entry
Identity comes first: CAS number and molecular formula. Molecular weight is given so a molar calculation can be done without leaving the page. Packing is the unit weight that is normally held; a different unit weight is a quotation item.
Where the catalogue entry does not state an assay, none is implied. Batch values are on the certificate of analysis, and a specification tighter than the catalogue entry is qualified before the lot is released.
Ordering a catalogue item
A gram-scale sample is the normal first order. It is quoted and shipped against the same specification as the kilo lot, so the analysis you see at the sample stage is the analysis you get at scale.
Kilo lots are dispatched with a batch COA, an SDS in GHS format and a specification sheet suitable for incoming inspection.
