One catalog, one set of records
Every listing shows the available sizes, the current price, and the documentation status for that material, so nothing has to be requested by email before ordering.

What each measurement can, and cannot, tell you.
Meridian publishes the methods behind its documentation rather than a single headline figure. Where a signed report exists for a lot, the lookup returns it; where one does not, the tool says so.
Identity by mass spectrometry
Mass measurement compares the observed molecular mass of a lot against the mass calculated from the stated sequence. A report worth reading gives both numbers and the instrument tolerance, rather than the single word conforms. Where tandem fragmentation is run, it adds sequence-level evidence rather than mass agreement alone.
What it cannot establish: Mass agreement does not quantify how much of the vial is the intended compound, and it cannot distinguish species of identical mass such as some sequence rearrangements.
Identity — limits
Mass agreement does not quantify how much of the vial is the intended compound, and it cannot distinguish species of identical mass such as some sequence rearrangements.
Chromatographic purity — limits
It measures relative peak area, not absolute content. Salts, counter-ions, residual solvent, water and endotoxin are largely invisible to it, and a co-eluting species is counted as the target.
Endotoxin — limits
It is not a sterility test. It says nothing about fungal contamination, Gram-positive organisms, or exotoxins, and a low figure does not mean a vial is sterile.
Appearance — limits
Neither establishes chemical identity or purity. An intact, dry cake can still be the wrong compound, and these checks describe the lot as inspected, not as it arrives after transit.
Volume pricing
Stocking a study? Per-vial pricing drops with the line quantity.
Tiers apply automatically in the cart — nothing to request and no code to enter.

Documentation lookup
Start with the code on the vial.
The verification tool returns a result only when a signed report is held for the entered lot. It does not substitute data from another batch.
Methods
Understand what HPLC, mass spectrometry and endotoxin screening measure.
Records
Match available documentation to the exact lot printed on a vial.
Limits
Read what each analytical method cannot establish before interpreting a report.
