04配方与处理要点
配方与处理要点
我们技术团队对采购本品的客户必讲的几件事——决定一批货在您工艺里能不能用起来的关键点。
01
The commercial logic of this ingredient is that one salt carries two actives down two different pathways: arginine feeds the nitric oxide synthase route and nitrate feeds the nitrate-nitrite-NO reduction route. That is why the 73%/27% split is the number formulators quote rather than the total salt weight.
02
Both numbers check out stoichiometrically, which is a useful sanity test on any offer: L-arginine 174.20 in a 237.21 g/mol mononitrate is 73.4%, and nitrate 62.00 is 26.1%. An offer whose stated split is far from 73/27 is either a different stoichiometry or wrong.
03
Nitrite is the specification row that matters most, and it is not on a standard amino-acid COA. Nitrite is a nitrosamine precursor and a toxicological endpoint of its own, so a nitrate salt needs a nitrite limit — insist on one before you formulate, not after.
04
Nitrate salts can be classified as oxidising solids for transport, which is a completely different shipping conversation from an amino acid. Confirm the UN classification, packing group and air-freight status from the manufacturer's MSDS before you quote a freight mode. This is the one SKU in the range where the logistics answer is not 'ships like a food powder'.
05
In a formulation containing secondary amines and a low pH, nitrate and especially nitrite raise a nitrosation question. It is a formulation-safety review item, not a reason to avoid the ingredient, but it should be on the record.
06
Nitrate contributes to a finished product's oral nitrate load, which is relevant if your customer's market regulates nitrate in food or if athletes in your customer base are subject to sport-specific monitoring. Give them the nitrate assay so they can do the arithmetic.

|---|---|---|
| United States | Arginine nitrate is not among the amino acids listed in 21 CFR 172.320 — that regulation covers amino acids 'in the free, hydrated, or anhydrous form, or as the hydrochloride, sodium, or potassium salts', and the nitrate salt is not one of them. No GRAS notice for arginine nitrate was identified. US supplement marketing rests on DSHEA and possibly on a New Dietary Ingredient notification. | 21 CFR 172.320(a) (salt forms covered); DSHEA / NDI framework |

09采购问答
采购问答
01Is this a branded nitrate ingredient?
No. We supply this as generic arginine nitrate and make no branded-ingredient claim. Branded nitrate ingredients exist in this space and are covered by their owners' trademarks and patents; if your formulation or label needs one, that licence has to come from the brand owner, not from us. What we can document is the material itself: assay, nitrate content, COA per batch and transport classification.
02How does the 73/27 split work out?
It is stoichiometric, which is a good sign: L-arginine is 174.20 of the 237.21 g/mol mononitrate, or 73.4%, and nitrate is 62.00, or 26.1%. So a 2000 mg serving is about 1470 mg arginine and 520 mg nitrate. Ask for both assays on the COA so you can dose against either number.
03What has to be on the COA for a nitrate salt?
Nitrite, above all — it is a nitrosamine precursor and a toxicological endpoint, and it does not appear on a standard amino-acid COA. Also both the arginine and nitrate assays separately, and heavy metals. We will request the manufacturer's nitrite limit and method with your quotation.
04Does it ship like your other powders?
Do not assume so. Nitrate salts can be classified as oxidising solids for transport, which changes the packing group, the documentation and potentially air-freight eligibility. We will confirm the UN classification from the manufacturer's MSDS before quoting a freight mode on this item.
05Arginine Nitrate 的起订量（MOQ）是多少？
MOQ按询盘灵活确定。在询盘中告知目标数量——核心现货SKU通常小试单与多吨位大单都可承接。
06下单前能否获取 Arginine Nitrate 样品？
可以——样品可按需提供，用于评估与实验室验证。在询盘中说明即可，我们逐单确认安排。
