Ordering at volume

This is a standard-catalog line with one fill, 50 mg, so every vial of it on an order counts toward one ladder and the volume and bulk breaks are reached by that count alone. Small molecules are dispensed by weighing rather than by freeze-drying a solution into the vial, which makes the fill accurate but also means the salt form must be fixed before the mass means anything: 50 mg of one salt contains a different amount of the cation from 50 mg of another.

The first thing to settle on a quote for this compound is therefore the salt, written out, and whether the fill is stated as salt or as cation. The second is the identity method: a small molecule is characterized differently from a peptide, and buyers with a specification should ask which technique the certificate reports before ordering. Most quotes for this line are returned within the business day and should restate both points.

Stock is held in California, so orders inside what is on the shelf ship in days while a larger order is given a date on the quote. Because it is a small molecule it does not need cold shipping, and the quote states how a mixed order travels.

What the material is

5-Amino-1-MQ is a small organic molecule, not a peptide: a quinoline ring system carrying an amino group at the 5-position and a methyl group on the ring nitrogen, which leaves that nitrogen positively charged and makes the compound a quinolinium salt. The counter-ion that balances the charge in a given lot is stated on the certificate rather than here, and the molecular weight is not restated because the figure depends on whether the cation alone or the whole salt is counted.

It does not look like the peptides. The appearance of each lot is recorded on its certificate; salts of aromatic amines are often coloured, so a coloured powder is not by itself a sign of a problem, and the material is a powder rather than a freeze-dried cake. The stocked fill is 50 mg, in a sealed glass vial.

Storage and reconstitution

Store the sealed vial cool, dry and in the dark; a refrigerator is sufficient and freezing is not necessary for a small-molecule salt, though it does no harm. Aromatic amines darken slowly in light and air, so the vial should stay closed and shaded, and an opened vial should be resealed promptly.

The salt dissolves in water and in polar organic solvents such as dimethyl sulfoxide, and its solutions are coloured. Water solubility is good for a charged aromatic compound; if a solution is slow to clear, brief gentle warming is usually enough.

Solutions are more stable than peptide solutions and can be kept refrigerated for a period, but light exposure is the main route of degradation and a darkening solution should be discarded. Freezing an aqueous solution is acceptable; a stock in dimethyl sulfoxide should be stored frozen and thawed only as needed.
